How do you guys determine when to change it? The color? Mileage? Age?
It's 100% that you got air in, and ran things dry doing it that way, but the air should have purged itself by now.Ok, I tried flushing mine, myself a few years ago. I took the return line off and put it to a container to catch the waste oil and plugged the hole for it in the tank. I had my dad start the engine for a few seconds while I tried to pour the new fluid in. I couldn’t keep up with how fast it pumped, but I must have poured in a couple quarts or more. But maybe a year later, a mechanic said that I needed a power steering flush. I do notice that the power steering is sometimes a little weird when cold since I flushed it. Is it possible the air I got in there caused damage?
